Title: Lens polishing device
Inventor: MAYAHARA KIYOSHI
IPC: B24B13/02
Filed: 1985-01-25
Abstract: PURPOSE:To aim at carrying out the polishing of lenses with no restriction by the diameter of lenses, and at simplifying the change-over of kinds of articles, by journalling the rotating center of a pressing pin to a horizontally movable plate, and by pressing a lens against a polishing pan by the horizontal and rotating motions of the horizontally movable plate, so that a rotary member is rotated in association with the horizontal displacement of the rotating center. CONSTITUTION:A lens 1 is reciprocatingly swung about a spherical center point C as a swinging center, by motors 21, 25. This is because a lens holding and pressing unit 14 is fixed onto a roatary shaft 16 which is rotated by the rotating motor 21 through an arm 15 and which is fitted to a horizontally movable plate 18 horizontally moved by the motor 25 so that the rotating center D of the shaft 16 reciprocates on the line E, and the shaft 16 is rotated by angle of theta in association with the displacement X of the rotating center D of the shaft 16 so that it inclines until it aligns with the line F connecting between the spherical center C and the rotating center D. Thus, by inclining the lens holding and pressing unit 14 in accordance with the displacement D, the pressing force F is always effected on an axis passing through the spherical center C, and therefore, the spherical center polishing may be carried out with no restriction by the radius of curvature. Thereby polishing may be carried out only by replacing the data of radius of curvature even if kinds of articles are changed over.
